Samsung Galaxy S Duos Review: It will teach you patience

Samsung Galaxy S duos S7562 was launched a year back and is now available at a price of INR 9k approx. in the local market.

Why we are reviewing this old phone?

The answer is very simple. It is now selling like hot cake in price segment of 7-10k INR. The cause of this increased public interest is mainly due to two reasons:

  1. It is a Samsung dual SIM smartphone.
  2. It is not very expensive and has appealing technical specifications.

Our Promise 

We review phones with an obsessive focus on the experience that really matters to you. We don’t care about specifications, we will tell you what you will really feel while using the phone. And needless to say, we maintain total integrity and truthfulness in our reviews.

Don’t Miss- Why We Are Different 

  • Samsung Duos phone with good after-sales support

  • Poor camera
  • Stale design
  • Performance issues
  • HD video playback not supported

User Experience

a. Design

The Galaxy S Duos looks similar to its Galaxy siblings and can be recognised as a galaxy smartphone even from a distance. So, you might want to keep it in a flip-cover as the Galaxy phones do not have a very good branding in terms of looks.

The back panel is made up of plastic having a texture on top making it non-glossy.  It can be removed very easily using the provided notch. However, care should be taken while keeping the phone on rough surfaces as they might scratch the backpanel.

 The build quality is not that impressive but being a Samsung smartphone it might survive a few non-facedown drops.

The curved edges offer a good grip making the phone suitable to hold with perspiring hands.

The 0.3 MP front camera along with other sensors are located at the left of earpiece grill.

b. User Interface

The Galaxy S duos runs on Samsung’s home brew TouchWiz user interface. While I like TouchWiz most of the times but in this case it doesn’t add much to the functionality of the device.

If you have joined the bandwagon of infinitesimal lags or if delays make you pull your hair then this phone is not for you.


c. Display

It sports a 4 inch TFT LCD display having a resolution of 480×800 pixels. The pixel density is 233 ppi which is more than acceptable for any phone at this price point.

The colors are a bit dull for enjoying a documentary shot in a national park. The images rendered by the display look sharp and wouldn’t make you feel that you are missing out on details.

Generally, from a budget smartphone we do not expect excellent viewing angles but the Samsung Galaxy S Duos surpassed our expectations and proved itself to be a good choice for watching a video among a group of friends.

d. Typing

You might be expecting that typing text messages on this phone should be fun. No, it is not.

The typing in portrait mode is not an easy task. Even the landscape mode will not satisfy your zest to compose a thousand word message.

At one instance during our typing test, the phone actually froze. Samsung, what have you done!

Thankfully, it is an android ICS device which is compatible with a lot of apps to save your ass in any situation. So, for elevating the typing experience and taking it to a next level, you can install apps like swipe, swiftkey etc.

The voice input is another option to enter the text when you’re too tired to type or when your hands are shivering.

e. Browsing

I would not recommend this phone to netizens. Here is why:

The browser takes a while before it renders media rich webpages containing a lot of images and flash content. Pinch to zoom is present but it takes a few seconds before it actually zooms onto the content.

Samsung, netizens don’t want to wait for the page to render.

The stock browser also has incognito mode so that you do not have to delete the history after that session of private browsing.

The bandwidth management function helps prevent heavy bills by keeping cellular data usage in check.

The camera UI is just like other Galaxy devices of the older generation. The camera can be operated very easily using only one hand.

Strangely, you cannot give any touch input to the camera.

The specification says Auto-Focus and it does auto-focus on its own. You just have to adjust your viewfinder according to the position of subject and then tap the shutter key.

Camera UI

 The video recording also lacks touch focus for obvious reasons. The funny part is the about video recording resolution. Being 640×480 pixels, it gives the impression that this camera is from the last decade.

The colors of the shots taken by this 5MP snapper are also nowhere near to what you see with your eyes. Though the images preserve good amount of details, you would not like a dull photograph.

Downscaled Camera Samples at 90% Quality

The HDR mode is absent but given the quality of captured images it would have been of no use.

Samsung has opted not to provide the Galaxy S Duos with any noise cancellation algorithms. The low-light shots taken without firing the LED flash suffer from noise. However when you use the flash in low-light scenarios the images will have some yellow tint.

Low-light Camera Samples

It also takes a good 2s to fire up the camera app. So, don’t even try to use this camera to capture those momentous moments during sports events.

Here are some camera benchmarks which might come in handy:

Camera start-up time ~ 2.15 s
Capture time ~ 2 s

The loudspeakers of this phone are not loud enough for you to even realize in a noisy environment that it is ringing.

The stock music player supports basic features like shuffle, repeat, audio equaliser etc.

It is needless to mention that a Samsung smartphone under the price tag of 10k INR will not support .flv and .mkv playback. It also doesn’t even support .avi video format which is a shame for a phone of this generation. Furthermore, this so called smartphone, the Galaxy S duos, is incapable of playing HD and full HD videos.
By the way, you can use the free MX Player app to play .flv, .mkv and .avi formats till 480p.


Hardware performance

If you thinking of making this smartphone your next multi-tasking partner then let me get one thing straight:

It is no good for multi-tasking.

 It runs out of its breath after opening just a few apps and will start lagging when you try to game on it while listening to your favourite track.

Here are some timing benchmarks which might come in handy:

Reboot time ~ 45.56s
Start-up time 39.18s

Apps & Games

The Samsung Galaxy S duos comes with very few pre-installed apps like ChatON, Chrome and Game Hub.
Google Chrome is definitely a very useful app but I cannot say the same about Chat ON and Game Hub.


Batterysamsung galaxy s duos S7562

If you are looking forward to buying this phone just because you thought it’d be useful to hold it in hands when the winter comes, then be prepared to be disappointed.

It doesn’t heat much even when you play games on it.


Samsung Galaxy Grand Quattro might prove to be a better heater in winters.


Here are some results of our battery testing:

Test Test Duration Loss in Battery Charge Estimated backup time
WiFi Browsing 12 mins 6% 200 mins
Video playback 10 mins 5% 200 mins
Temple Run Oz (medium) 10 mins 6% 167 mins





As far as battery backup is concerned, the Power Saving Mode will prove to be highly useful.

The Galaxy S Duos is equipped with all of the standard connectivity options like 3G, 2G, WiFi with support for hotspot and WiFi Direct, Bluetooth, FM Radio, GPS with support for A-GPS and micro USB 2.0.

It can keep 2 GSM SIMs online in a dual SIM dual standby configuration. This is another feature which attracts buyers to this phone.

Final Verdict

S Duos stands for Double Stupidity

If you have read the whole review then you know why not to buy this phone. But if I were a Samsung fan then I’d buy this phone because it is a dual SIM android ICS phone. For others looking for a good dual SIM smartphone in the same price segment, the Xolo Q700 is worth a choice.

  • A Samsung Galaxy series fanatic
  • Want a branded dual SIM phone

  • Love gaming
  • Watch FHD videos
  • Travel to crowded places frequently
  • Like photography
  • Can’t tolerate performance lags
